Analysis

Our model puts a Benfica win at 38.5% in this Primeira Liga fixture — close to a three-way split. Expected goals run 1.29 to 1.36.

What this probability has been worth

A number is worth what it has been worth. Across 1,354 predictions published before kick-off and scored against the result afterwards, the calls we priced between 35% and 45% came in 39.6% of the time — 520 fixtures in that band. The model claimed 40.5%, so the two are within 0.9 points of each other. In this range the stated probability has meant roughly what it says.

Evenly rated

There is almost nothing between these two on rating — 1775 against 1804, a gap of 29 points. Fixtures this evenly matched are where a model has least to say: the probabilities below are honest, but they are close to a coin weighted only slightly.

Benfica are on a run

Benfica arrive on 6 straight wins, part of 18 matches unbeaten. Form of that length moves our rating on its own, so it is already reflected in the numbers above rather than being an argument on top of them.

How often they shoot

Benfica take 19.5 shots a match against an average of 11.8. Volume like that usually means territory rather than precision, and it is why a side can dominate a match and still not win it.
